Update maps manually (MN3)

Officially, maps on Media Nav should be managed using the Media Nav Toolbox. Yet, there are many cases – like already having acquired the maps or simply wanting to use free crowd-sourced maps – where an alternative would be more viable. This can be achieved, although it needs a little more work.

The navigation software used in Media Nav is iGO Primo, so your files must be compatible.

Note: Third generation Media Nav units (MN3) have two versions, AV and AVN. While both can use navigation, the AVN version has about 4 GB of space available for maps and additional files, while the AV version has only ~700 MB. This is enough for all countries, including Russia, but the number of neighboring countries will be rather limited, depending on the choice of maps and additional files. When adding new maps, file sizes should be taken into account.

Guide

Note: This guide applies only to third generation Media Nav units (MN3), firmware versions 1.0.X.X or higher (X denotes any digit from 0 to 9). For first and second generation Media Nav units (MN1 & MN2), see Update maps manually (MN1 & MN2).

Prerequisites:
– a tablet, laptop or desktop equipped with an USB port, containing the new maps
– USB flash drive, FAT32 formatted, min. 4 GB & max. 32 GB capacity, ideally with an indicator light

Note: An USB flash drive with an indicator light is preferred since the light will be the only indicator of the ongoing read and write operations performed on the flash drive.

Part 1 (optional) – Navigation Backup

Step 1. Download Navi Backup from the link in the table below.

Program NameFirmware VersionDownload Link
Navi Backup1.0.X.X
2.0.X.X
3.0.X.X
DOWNLOAD
Note: X denotes any digit from 0 to 9.

Step 2. Unzip the archive and copy the folders to the root of the flash drive – the folders should be the first to be seen upon accessing the flash drive.

Step 3. Put the flash drive in the USB port, start the car engine, wait for the Media Nav to boot and the backup will start automatically. Engine should be left running while the transfer is ongoing.

Step 4. When the indicator light of the flash drive stops blinking for 10-15 seconds or, if there is no indicator light, after about 15 minutes, you can unplug the flash drive, turn off the Media Nav and stop the engine.

Step 5. Copy the contents of nng_rw and nng2 on your tablet, laptop or desktop and delete them from the flash drive, leaving it empty. This will be the navigation backup, in case it may be needed later.

Part 2 – Current navigation files

Step 1. Download Navi Sync from the link in the table below.

Program NameFirmware VersionDownload Link
Navi Sync1.0.X.X
2.0.X.X
3.0.X.X
DOWNLOAD
Note: X denotes any digit from 0 to 9.

Step 2. Unzip the archive and copy the folders to the root of the flash drive.

Step 3. Put the flash drive in the USB port, start the car engine, wait for the Media Nav to boot and the backup will start automatically. Engine should be left running while the transfer is ongoing.

Step 4. When the indicator light of the flash drive stops blinking for 10-15 seconds or, if there is no indicator light, after about 15 minutes, you can unplug the flash drive, turn off the Media Nav and stop the engine.

Note: Indeed, mostly the same files were copied as in Part 1, with the notable difference that this are the files we will work on.

Part 3 – Update navigation files

Step 1. Download Navi Update from the link in the table below.

Program NameFirmware VersionDownload Link
Navi Update1.0.X.X
2.0.X.X
3.0.X.X
DOWNLOAD
Note: X denotes any digit from 0 to 9.

Step 2. Unzip the archive and copy the folders to the root of the flash drive, merging autorun_bavn and nng folders, overwriting files if necessary.

Step 3. Copy your maps and additional files to the nng folder on the flash drive, with respect to the following structure:

/NNG

|---data.zip - GUI elements, usually for certain resolutions
|---branding.zip - misc icons
|---sys.txt - config file

Notes:
1. The bare minimum in order for a country’s map to be usable is the *.fbl file. Depending on your map provider, the files may already be organized as above.
2. *.dem files are not supported in this version.
3. Speedcam files will be added separately, do not add them at this step.
4. The nngnavi file, together with the licenses, found in the archive, enable the use of free or previously acquired maps, as long as they are compatible with iGO Primo.

Step 4. Put the flash drive in the USB port, start the car engine, wait for the Media Nav to boot and the backup will start automatically. Engine should be left running while the transfer is ongoing.

Step 5. When the indicator light of the flash drive stops blinking for 10-15 seconds or, if there is no indicator light, after about 15 minutes, you can unplug the flash drive, turn off the Media Nav and stop the engine.

At this point, the maps and additional files have been updated and ready to use, with the exception of speedcams, which require a slightly different transfer procedure, detailed below.

Part 4 (optional) – Update speedcams

Step 1. Download Navi Speecams from the link in the table below.

Program NameFirmware VersionDownload Link
Navi Speedcams1.0.X.X
2.0.X.X
3.0.X.X
DOWNLOAD
Note: X denotes any digit from 0 to 9.

Step 2. Empty the flash drive if there are any previous files, unzip the archive and copy the folders to the root of the flash drive.

Step 3. Copy your speedcam files, *.spc or *.txt, on your flash drive to nng/content/speedcam.

Step 4. Put the flash drive in the USB port, start the car engine, wait for the Media Nav to boot and the backup will start automatically. Engine should be left running while the transfer is ongoing.

Step 5. When the indicator light of the flash drive stops blinking for 10-15 seconds or, if there is no indicator light, after about 3 minutes, you can unplug the flash drive, turn off the Media Nav and stop the engine.

At this point, the speedcams are, also, ready to use. While the steps are almost the same as for the other files, to script that handles the copying includes a handful of additional operations.

Troubleshooting

After each part, a log is created – a *.txt file – that contains the details of the files transfer, which may give clues for problems that may eventually appear. This log will be found in the root of the flash drive, after unpluging it from the USB port.

If there is a problem with GPS positioning – for example, the arrow doesn’t move (appears frozen) – resetting the save folder may fix this situation. For this, see Resetting the navigation save folder (MN3).

Additional problems may require the navigation software (more specifically, its files) to be diagnosed first. For third generation Media Nav units, see Navi Diag (MN3).
